Ortho Evra - I started evra this month. I'm on my week four, patch off week. I think I may possibly?

... be pregnant. My breasts have been swollen and soreall last week, and i feel bloated this week. Also, about a week and a half ago i had my wisdom teeth out. I informed them i was on the patch and they assured me that it wouldnt be a problem. I was on t3's and amoxicillin and have been using an anti bacterial mouthwash. I'm hoping nothing interfered. But i'm extremely paranoid that i might be pregnant. This is the end of day two with out the patch.I've been pregnant before and it feels very similar. Should i start my patch again if i suspect i might be pregnant, especially with no bleeding?
